What happens to the food when it is converted to bolus?

When food is converted to a bolus, it undergoes mechanical and chemical processes in the mouth. Chewing breaks the food into smaller pieces, while saliva, containing enzymes, begins the digestion of carbohydrates. The resulting soft, moist mass is then pushed to the back of the throat and swallowed, making it ready for further digestion in the esophagus and stomach. This transformation is crucial for efficient digestion and nutrient absorption.
